[Matthieu Wipliez]

Hi Philip,

You cannot perform arithmetic computations with StringTemplate, so these must be 
put in the model:

1) I would say add a method isEven() in the model and use
class="$if (row.even)$even$else$odd$endif$"

2) You must define a method getHalfPrice() { return price / 2; }
and use it in the template.

Cheers
Matthieu
